cocosbuilder3.0 bug修正：解决在帧上添加音效预览时经常没声音的问题

究其根本，发现是float变量的值比较问题，所以改法如下

文件 SequencerNodeProperty.m

函数keyframesBetweenMinTime

改成

const float EPSINON =
0.0000001;
- (NSArray*) keyframesBetweenMinTime:(float)minTime maxTime:(float)maxTime
{
NSMutableArray* kfs = [NSMutableArray
array];
for (SequencerKeyframe* keyframe
in keyframes)
{
float leftF = keyframe.time-minTime;
float rightF = maxTime-keyframe.time;
if ((leftF>=0||fabs(leftF)<=EPSINON) &&(rightF>=0||
fabs(rightF) <= EPSINON))
{
[kfs addObject:keyframe];
}
}
return kfs;
}

其中的 if ((leftF>=0||fabs(leftF)<=EPSINON) &&(rightF>=0|| fabs(rightF) <= EPSINON)) 就是关键所在，替换原有的大于等于和小于等于
